num_array (empty number array)


num_array() -> Array<Number>

Returns an empty array meant for numbers. Used as a helper function to allow shorthand arithmetic operators +, -, *, /, and ^ to be used with the resulting array.

Example:


local custom_array = {8, 9}
 
local proper_array = num_array()
proper_array[1] = 8
proper_array[2] = 9
 
local t = proper_array + {3, 4} -- this is OK
 
local t = custom_array + {3, 4} -- this will produce an error
 
local t = proper_array - custom_array -- this is OK again
